1 Gigawatt = 1000 Megawatt

Key Formulas

Kilowatt → Horsepower (mech)

hp = kW × 1.34102

Horsepower (mech) → Kilowatt

kW = hp × 0.7457

Watt → Kilowatt

kW = W × 0.001

Kilowatt → Watt

W = kW × 1000

Formula

MW = GW × 1000

One gigawatt equals exactly 1,000 megawatts. This conversion describes utility-scale power generation and national grid capacity. Gigawatts quantify the total electrical infrastructure of countries and continents; megawatts describe individual power plants. Understanding this hierarchy is essential for energy policy, renewable energy planning, and understanding grid capacity discussions.

Real-World Examples

National renewable energy capacity: 1 GW = 1,000 MW of solar/wind infrastructure.

1 GW = 1000 MW

Large country grid (e.g., UK) total fossil capacity ~60 GW = 60,000 MW baseload power.

2 GW = 2000 MW

Regional power pool: 0.5 GW = 500 MW peak capacity serving 300,000-500,000 people.

0.5 GW = 500 MW

Major nation wind energy target: 5 GW = 5,000 MW offshore and onshore combined.

5 GW = 5000 MW
